Thirteenth Report of 
principle into the construction of the eye-piece by attaching 
the cells to the tubes by cylindrical fittings. 
Here, Gentlemen, I would willingly conclude ; but I have 
still the melancholy duty remaining of recording the death of 
three of our members, a duty from which my predecessor was 
last year happily exempted. 
Of Mr. Edward Stokes I had no personal knowledge ; but 
I have been informed that he was a zealous cultivator of 
science. 
Mr. Dalrymple and Dr. Mantell have both left names which 
will not speedily be forgotten, and which merit a much more 
extended notice than it is in my power to give. 
John Dalrymple was the eldest son of William Dalrymple, 
a highly distinguished surgeon at Norwich, under whom he 
received the early part of his professional education. He 
afterwards studied at the University of Edinburgh, and in 
1827 became a member of the Royal College of Surgeons in 
London, and settled in the city. In 1832 he was elected 
Assistant-Surgeon to the Royal Ophthalmic Hospital, and 
Surgeon in 1843. In 1847 he retired from that office on 
account of ill health, and was appointed Consulting Surgeon. 
In 1851 the Fellows of the Royal College of Surgeons elected 
him a Councillor. He published a work on the Anatomy of 
the Eye in 1834 ; and a splendid one on the Pathology of 
that organ he only just lived to complete. In fact, he revised 
the last number but a few days before his death. His style 
is clear and concise ; and the soundness and precision of his 
views, and the accuracy of his delineations, are universally 
acknowledged by the profession. In 1839 he removed from 
the city to the west end of London, where his practice in- 
creased, and latterly had become greater than was compatible 
with the state of his health. In addition to his own peculiar 
department of surgery, in which he had attained the highest 
eminence and the full confidence of the profession, he suc- 
cessfully prosecuted the delicate and interesting science of 
microscopical anatomy, both human and comparative. He 
was an original member of this Society, and one of our first 
council ; and he contributed a valuable paper " On the Ar- 
rangement of the Capillary Vessels of the Allantoid and Vitel- 
line Membranes in the incubated Egg " to the first volume of 
our Transactions. Until illness obliged him to spend his 
evenings at home, he was a frequent attendant at our meet- 
ings ; and his remarks, when he took a part in our discus- 
sions, were characterised not less by clearness and precision 
than by the modest and gentlemanly tone in which they were 
delivered.
